what is measure of angle r?

enter your answer as a decimal in the box. round only your final answer to the nearest hundredth.

There are a variety of ways you can solve this. I'll use the sine trig function.

If the = you can simply put into a scientific calculator and press "sin-1" to get an answer of approximately 28, which means that angle R is 28°

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
